The Twilight star appeared on GMA Wednesday morning, where interviewer George Stephanopoulos presented him with a box of Cinnamon Toast Crunch and gently prompted him to address "the elephant in the room."

"Everybody just wants to know, how are you doing?" Stephanopoulos asked. "And what do you want your fans to know about what's going on in your personal life?"

Pattinson stammered and shifted in his seat uncomfortably before turning his attention back to the cereal box.

"I'd like my fans to know that Cinnamon Toast Crunch only has 30 calories a bowl," he quipped, before adding: "Pretty much everything that comes out of my mouth is irrelevant."

Pattinson was equally reticent with Stewart, and told Stephanopoulos Wednesday in no uncertain terms that he wasn't interested in discussing his love life.

"You get into it to do movies," said Pattinson, who was on the morning show to promote his new film, Cosmopolis. "I've never been interested in trying to sell my personal life. ... The reason why you go on TV is to promote movies."

Asked by Stephanopoulos if he'll ever get used to the media scrutiny, Pattinson responded, "If you start getting used to it, it means you're going crazy."
